git: make it work on the target

git: make it work on the target

Packaging is synced with OE .dev, but without the -large, thanks to pseudo we retain all (hard)links properly:

* git-perltools holds all the utils requiring perl and adds appropriate RDEPENDS
* git-tk holds the tcl/tk utils once they get activate
* git now packages /usr/libexec/git-core

The result:
